Somersault kick only has two different character frames during the actual attack. One looks to be the "float" or "fly" animation while the second is one of the weapon swing or stab ones. The first has been flipped 180 degrees while the second has been turned 90 degrees.
Rotating a sprite to any multiple of 90 degrees should be pretty trivial. Hell, Microsoft Paint has done it for over a decade, no problem.
Photoshop is just over thinking it.
I have no idea how efficient converting to a raster version of the images would be, but they can always clean up any sprite versions and add those solid lines.
Since they're converting to relatively simple images anyway, they probably don't even use anti-aliasing.
I'm more of the opinion that the images begin as hand-drawn anyway. Just presented vectors as an option since I know that's how some developers do/did it.
It's just highly unlikely that they're hand-crafting any of the sprites in the game.
It takes too much time.
